Description

Electronic Power Conversion Application Test Solutions

NH Research, Inc. (NHR) has designed, built, installed and supported industry leading test instrumentation and turnkey test systems world-wide for over 50 years. Both instruments and systems are typically used to functionally test a wide variety of customer’s power conversion devices at either the research & development stage or at the end of a customer’s production line as the final check that their product is meeting all its specifications. In both functional areas, NHR provides highly flexible configurations, ease of programming, comprehensive measurement capability and exceptional test throughput.

Some of the application test solutions NHR covers include the following:

Charger & Adapter Test

Charger and adapter testing is another area where being competitive demands hyper-fast testing. Testing one unit at a time or even a handful of units at a time simply isn’t competitive anymore. NHR meets that requirement with its Model 600 Test System and its ability to test up to 16-units in a single pass. An added benefit is that the Model 600 has the smallest form factor in the industry, which makes it easy to integrate into a conveyor-based production line.Multi-Channel Testers – S600 Series

DC Power Supply Testing

DC Power Supply Testing, the original test system business of NHR, is now in its 4th generation with 4 types of testers:
The S400 Series – a compact production tester in 3 sizes for small-to-medium power levels
The S600 Series – the newest tester with capability of testing from 1 to 16 channels in parallel with complete precision measurements
The 5600 Universal Tester – a highly flexible tester that can be custom configured to meet the test requirements of a wide range of DC supplies
The 5700 Engineering Characterization Tester – When performing design verification tests or just seeking more extensive testing of high-reliability power supplies all the tools are here to achieve both comprehensive testing and reporting almost immediately.

LED Power Driver Testing

The LED industry is highly competitive, achieving the lowest cost of test is usually one of the most important factors in selecting a tester. NHR meets that requirement by being able to fully test up to 16-units in a single pass. NHR equipment required is a Model 600 Test System. Note that due to the single-card form factor for most channel instrumentation, a 16-unit tester will fit within a 30”-high cabinet.Multi-Channel Testers – S600 Series

PV/DG Grid Tied Inverter Testing

NH Research, Inc. (NHR) provides test equipment for PV/DG Grid Tied Inverter Testing which can simulate the utility connection as well as energy storage devices.
The NH Research, Inc. 9410 Grid Simulator can provide a 1Φ, 2Φ, or 3Φ simulated utility connection while allowing per-phase controls for amplitude, wave shape, & the relative to a phase angle relationship. These features allow testing of any number of AC conditions including phase imbalance (in voltage and/or phase angle relationship), voltage sag, frequency changes, & harmonic injection. The included measurement system removes the need for an additional power meters, DMMs, oscilloscopes, or spectrum analyzers.
The 9200 Battery Test System includes a charge mode, a discharge mode, & a state of the art battery emulation mode which allows testing of a battery or electronically-emulating a battery. Using battery emulation replaces a real battery thereby eliminating risks associated with a battery failure even those potentially caused by a unit-under-test (UUT) failure. Additionally, battery emulation produces faster and more consistent testing by eliminating battery-related preparation time, operator errors, ∓ result variations due to temperature or aging.Regenerative Grid Simulator – Model 9410Battery Module/Pack Test System – 9200 Series
